domain of (3x+4)/(x^2-25)

domain

\frac{3 x + 4}{x ^{2} - 25}

x < - 5 or - 5 < x < 5 or x > 5

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

x < - 5 or - 5 < x < 5 or x > 5

f (x) = 3 y - x = 3

f (x) = \frac{3 x ^{2} - 5 x - 2}{x ^{2} - 4}

2^{x - 1} + 2

\frac{2 x ^{2} + 16 x - 18}{x ^{2} + x - 6}

x^{3} - 3 x

What is the domain of (3x+4)/(x^2-25) ?
The domain of (3x+4)/(x^2-25) is x<-5\lor-5<x<5\lor x>5
